FIGURE 8 in A new ornithopod dinosaur, <i>Transylvanosaurus platycephalus</i> gen. et sp. nov. (Dinosauria: Ornithischia), from the Upper Cretaceous of the Haţeg Basin, Romania
FIGURE 8. Strict consensus tree of the first phylogenetic analysis performed by us using the matrix of Madzia et al. (2018), showing the relationships of Transylvanosaurus platycephalus within Ornithischia and Ornithopoda. Notably, the phylogenetic relationships within Rhabdodontidae as shown herein differ from those reconstructed based on our thorough morphological comparisons (i.e., a particularly close relationship between Transylvanosaurus and Rhabdodon). Due to the scarcity of relevant braincase characters in the original dataset and the poor resolution of Rhabdodontidae, we regard the hypothesis derived from the morphological comparisons as more likely.
